After writing the Visual Studio 2010 iso image on a disk or mounting the .iso setup file as a new drive on your operating system, the Visual Studio 2010 installation can be easily done.

I use Gizmo for mounting ISO files. For my Microsoft Visual Studio 2010 installation, I also preferred Gizmo to mount .iso image. It is important that you should configure the vs2010 download .iso to remount image when the Windows starts up again. Because during the VS2010 installation Windows will reboot after .NET Framework 4.0 installation.

When you place the Microsoft Visual Studio 2010 setup DVD on CD drive or mount .iso image, the VS2010 Setup Wizard will display automatically the below screen where IT professionals can start VS 2010 Ultimate installation.

When you start the installation by clicking the "Install Microsoft Visual Studio 2010" link on the above screen the installation wizard will start first by loading installation components.
